Open Source C Audio Analysis Software - Page 2

ManyEars implements real-time microphone array processing to perform sound source localisation, tracking and separation. It was designed for mobile robot audition in dynamic environments. NOTE: Development will continue on github : https://github.com/introlab/manyears

The Analysis & Reconstruction Sound Engine analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.

FFT Spectra is a tool for visualization of frequency spectra of an audio signal. What is it good for? For instance, you can verify whether you are able to sing and whistle in-tune or tune your guitar.

Onset detector for musical signals, with an emphasis on real-time onset detection for interactive music systems. Hence this aims to be a small, efficient, lightweight onset detection system that provides good-quality detection.

OpenTranscribe is a software to aid musicians in transcribing music. It lets you slow down a part of the music without affecting pitch. It also lets you loop over a section which have some tricky parts.

This project is a Free Software implementation of reccomandation ITU-R.BS.1387 that provide to describe the algorithm of - Perceptual Evaluation of Audio Quality - (PEAQ).

Automatic cutter and mp3 converter of captures from TV music channels

Sonogram and waveform display programm for Unix using different algorithms like FFT and LPC to display musical features or potential artefacts that you may no be able to hear. Superimposed tuneable Staff-Lines allow for easy transcription of music.

VisualCube is a volumetric display out of 6*6*6 voxels, where each voxel get's represented by a 2-color LED. This project includes a bunch of tools used to control this peace of hardware, by taking advantage of the VisualCube library.

This program takes audio input from microphone, you can redirect pc audio output using control panel on Windows or pavucontrol on Linux. Your computer needs to support openCL (is sufficient a modern gpu or a intel core cpu) Commands: F11 toggle fullscreen S toggle stroboscopic flash NUMBER [0 to 9] change number of symmetry axes

A real-time 3d sound spectrum analyzer for linux.

Instrument tuner. It can help you to tune a piano, a guitar ... Accordeur displays spectrum and calculates the pitch really played. A visual bar allows an easy tuning. Instruments and temperaments are customizable.

This is a toolbox for speech processing written in C. It realizes interface of Voicebox toolbox (http://www.ee.ic.ac.uk/hp/staff/dmb/voicebox/voicebox.html).

Chord Reporter (hereafter abbreviated to CR) is a software program that displays the names of chords, as you play them (upon some MIDI controller or from a MIDI sequencer track). CR comes in two versions. There is an LV2 plugin that will run on any Linux program that loads such plugins. In that way, you can anaylze the chord progressions in your DAW's MIDI tracks. The second version is a Linux executable that runs on its own. You can directly attach your MIDI controller to this version to review the chords you're playing (as you play them). A suitable MIDI controller would be either a MIDI keyboard, a guitar equipped with a MIDI pickup such as the Fishman triple play, or even an electric guitar pickup plugged into a computer audio interface running pitch-to-MIDI software.

A set of tools for psychoacoustic research. Initially implemented: * correlograms (and sonograms too) * Lyons' cochlear model * impulse-domain transform using FIR filters (and inverse transform)

Native MacOSX realtime, Altivec powered sound processing application

The project aims to identify a simple and low cost eddy current probe that can be interfaced directly to ordinary linux systems and develop software to record data and identify hidden corrosion on aircraft during their mandated annual inspections.

Csound is a sound and music synthesis system, providing facilities for composition and performance over a wide range of platforms. It is not restricted to any style of music, having been used for many years in at least classical, pop, techno, ambient. Csound is now hosted at https://github.com/csound Binary and source-code releases: http://csound.github.io/download.html Mailing lists are hosted by HEAnet at https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND and https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND-DEV Archives: mail lists at http://dream.cs.bath.ac.uk/Csound-archive releases: http://dream.cs.bath.ac.uk/Csound-archive/OldReleases/

A Client-/Server-based Audio Player System for use in discos as well as at home.

a continuous monitoring device that uses Real-Time DSP techniques to discern barking against a noisy environment and only record the sequences of barking and their corresponding time and dB levels.

This project implements the MPEG-7 Audio Spectrum Envelope and Audio Spectrum Projection descriptors.

Easy-to-use platform-independent plugin API for the extraction of low-level features from audio data in PCM format, as required in the context of music information retrieval software.

Freetantrum is an umbrella codename for the open-source projects of eTantrum, Inc, including the eTantrum Songprint music identification library.

Funiculus is a guitar tuner for the iPhone. It analyzes the frequency of a note played and provides feedback to the user.
